BACKGROUND

Through oxidative phosphorylation, mitochondria convert nutrients and oxygen into adenosine triphosphate (ATP), the chemical transporter of energy in most aerobic organisms. The electron transport chain (ETC) of the mitochondria represents the primary source of ATP, as well as a source of reactive oxygen species (ROS). Mitochondrial dysfunction results in less ATP production and, as a result, insufficient energy to maintain the cell. Such dysfunction also results in excessive ROS production, spiraling cellular injury, and ultimately apoptosis of the cell. Mitochondrial dysfunction, is a key element believed to be at the root of a variety of serious, debilitating diseases.

Natural antioxidants such as coenzyme Q and vitamin E have been shown to provide some protection of the cell from damage induced by elevated ROS levels associated with mitochondrial dysfunction. However, antioxidants or oxygen scavengers have also been shown to reduce ROS to unhealthy levels and may not reach the ETC in sufficient concentrations to correct the mitochondrial imbalance. Therefore, there is a need for novel compounds that can selectively target the ETC, restore efficient oxidative phosphorylation, and, thereby, address mitochondrial disease and dysfunction.

DETAILED DESCRIPTION

The present invention features salts of Compound I

Arg-Dmt-Lys-Phe-NH₂). Compound I has been shown to affect the mitochondrial disease process by helping to protect organs from oxidative damage caused by excess ROS production and to restore normal ATP production.

A crystalline form of a salt of Compound I can be used to modulate/improve the physicochemical properties of the compound, including but not limited to solid state properties (e.g., crystallinity, hygroscopicity, melting point, or hydration), pharmaceutical properties (e.g., solubility/dissolution rate, stability, or compatibility), as well as crystallization characteristics (e.g., purity, yield, or morphology).

In certain embodiments, the present invention provides a pharmaceutical preparation comprising a crystalline salt of Compound (I) and one or more pharmaceutically acceptable excipients. In certain embodiments, the pharmaceutical preparations may be for use in treating or preventing a condition or disease as described herein.

In certain embodiments, the polymorph of the crystalline salt is characterized by powder X-ray diffraction (XRPD). θ represents the diffraction angle, measured in degrees. In certain embodiments, the diffractometer used in XRPD measures the diffraction angle as two times the diffraction angle θ. Thus, in certain embodiments, the diffraction patterns described herein refer to X-ray intensity measured against angle 2θ.

In certain embodiments, a crystalline salt of Compound (I) is not solvated (e.g., the crystal lattice does not comprise molecules of a solvent). In certain alternative embodiments, a crystalline salt of Compound (I) is solvated. In some cases, the solvent is water.

Methods of Making the Crystalline Salts

In certain embodiments, the invention relates to a method for the preparation of a crystalline salt of a compound having the structure of formula (I), comprising a) providing a freebase mixture of a compound of formula (I) in a first organic solvent; b) contacting the freebase mixture with a reagent solution comprising an acid and optionally a second organic solvent under conditions sufficient to form a mixture comprising a salt of the compound of formula (I); and c) crystallizing the salt of the compound of formula (I) from the mixture comprising a salt of the compound of formula (I).

In certain embodiments, the invention relates to a method for the preparation of a crystalline salt of a compound having the structure of formula (I), comprising a) providing a first salt mixture of a compound of formula (I) in a first organic solvent; b) contacting the first salt mixture with a reagent solution comprising an acid and optionally a second organic solvent under conditions sufficient to form a mixture comprising a second salt of the compound of formula (I); and c) crystallizing the second salt of the compound of formula (I) from the mixture comprising a second salt of the compound of formula (I).

In certain embodiments, the invention relates to a method for the preparation of a crystalline salt of a compound having the structure of formula (I), comprising a) providing a first mixture comprising a protected form of a compound of formula (I) in a first organic solvent; b) contacting the first mixture with a reagent solution comprising an acid and optionally a second organic solvent under conditions sufficient to deprotect the protected form of the compound of formula (I) and to form a mixture comprising a salt of the compound of formula (I); and c) crystallizing the salt of the compound of formula (I) from the mixture comprising a salt of the compound of formula (I).

In certain embodiments, the mixture comprising a salt of the compound of formula (I) formed in step b) is a solution. In certain embodiments, the mixture formed in step b) is a slurry or a suspension.

In certain embodiments, the mixture comprising the salt of the compound of formula (I) is a solution, and the step of crystallizing the salt from the mixture comprises bringing the solution to supersaturation to cause the salt of the compound of formula (I) to precipitate out of solution.

In certain embodiments, bringing the mixture comprising the salt of a compound of formula (I) to supersaturation comprises the slow addition of an anti-solvent, such as heptanes, hexanes, ethanol, or another polar or non-polar liquid miscible with the organic solvent, allowing the solution to cool (with or without seeding the solution), reducing the volume of the solution, or any combination thereof. In certain embodiments, bringing the mixture comprising the salt of a compound of formula (I) to supersaturation comprises adding an anti-solvent, cooling the solution to ambient temperature or lower, and reducing the volume of the solution, e.g., by evaporating solvent from the solution. In certain embodiments, allowing the solution to cool may be passive (e.g., allowing the solution to stand at ambient temperature) or active (e.g., cooling the solution in an ice bath or freezer).

In certain embodiments, the preparation method further comprises isolating the salt crystals, e.g., by filtering the crystals, by decanting fluid from the crystals, or by any other suitable separation technique. In further embodiments, the preparation method further comprises washing the crystals.

In certain embodiments, the preparation method further comprises inducing crystallization. The method can also comprise the step of drying the crystals, for example under reduced pressure. In certain embodiments, inducing precipitation or crystallization comprises secondary nucleation, wherein nucleation occurs in the presence of seed crystals or interactions with the environment (crystallizer walls, stirring impellers, sonication, etc.).

In certain embodiments, the freebase mixture of a compound of formula (I) in a first organic solvent is a slurry. In certain embodiments, the freebase mixtures of a compound of formula (I) in a first organic solvent is a solution.

In certain embodiments, the first organic solvent and the second organic solvent, if present, comprise acetone, anisole, methanol, 1-butanol, 2-butanone, iso-butanol, tert-butanol, sec-butanol, cyclopentyl methylester (CPME), benezotrifluoride (BTF), 1-propanol, 2-propanol (IPA), water, dichloromethane, anisole, acetonitrile, ethylene glycol, tert-butyl methyl ether (t-BME), DMSO, ethylene glycol, toluene, tetrahydrofuran (THF), heptane, acetonitrile, N,N-dimethylacetamide (DMA), dimethylformamide (DMF), dimethylsulfoxide (DMSO), 1,4-dioxane, 2-ethoxy ethanol, heptane, isopropyl acetate, methyl acetate, 2-methyl THF, methyl isobutyl ketone (MIBK), 1-propanol, ethanol, ethyl acetate, hexanes, methyl acetate, isopropyl acetate, methylethyl ketone, 1,4-dioxane, methyl cyclohexane, N-methyl-2-pyrrolidone (NMP), or any combination thereof.

In certain embodiments, washing the crystals comprises washing with a liquid selected from anti-solvent, acetonitrile, ethanol, heptanes, hexanes, methanol, tetrahydrofuran, toluene, water, or a combination thereof. As used herein, “anti-solvent” means a solvent in which the salt crystals are insoluble, minimally soluble, or partially soluble. In practice, the addition of an anti-solvent to a solution in which the salt crystals are dissolved reduces the solubility of the salt crystals in solution, thereby stimulating precipitation of the salt. In certain embodiments, the crystals are washed with a combination of anti-solvent and the organic solvent. In certain embodiments, the anti-solvent is water, while in other embodiments it is an alkane solvent, such as hexane or pentane, or an aromatic hydrocarbon solvent, such as benzene, toluene, or xylene. In certain embodiments, the anti-solvent is ethanol.

In certain embodiments, washing the crystals comprises washing the crystalline compound of formula (I) with a solvent or a mixture of one or more solvents, which are described above. In certain embodiments, the solvent or mixture of solvents is cooled prior to washing.

Pharmaceutical Compositions

In certain embodiments, the present invention relates to pharmaceutical compositions comprising a crystalline compound or salt of a compound of formula (I) and one or more pharmaceutically acceptable excipients.

Exemplary pharmaceutically acceptable excipients are presented herein, and include, for example binders, disintegrating agents, lubricants, corrigents, solubilizing agents, suspension aids, emulsifying agents, coating agents, cyclodextrins, and/or buffers. Although the dosage could vary depending on the symptoms, age and body weight of the patient, the nature and severity of the disorder to be treated or prevented, the route of administration and the form of the drug, in general, a daily dosage of from 0.01 to 3000 mg of the compound is recommended for an adult human patient, and this may be administered in a single dose or in divided doses. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound which produces a therapeutic effect.

The precise time of administration and/or amount of the composition that will yield the most effective results in terms of efficacy of treatment in a given patient will depend upon the activity, pharmacokinetics, and bioavailability of a particular compound, physiological condition of the patient (including age, sex, disease type and stage, general physical condition, responsiveness to a given dosage, and type of medication), route of administration, etc. However, the above guidelines can be used as the basis for fine-tuning the treatment, e.g., determining the optimum time and/or amount of administration, which will require no more than routine experimentation consisting of monitoring the subject and adjusting the dosage and/or timing.

In certain embodiments, the individual to which the composition is administered is a mammal such as a human, or a non-human mammal. When administered to an animal, such as a human, the composition or the compound is preferably administered as a pharmaceutical composition comprising, for example, a compound of the invention and a pharmaceutically acceptable carrier. Pharmaceutically acceptable carriers are well known in the art and include, for example, aqueous solutions such as water or physiologically buffered saline or other solvents or vehicles such as glycols, glycerol, oils such as olive oil, or injectable organic esters. In a preferred embodiment, when such pharmaceutical compositions are for human administration, particularly for invasive routes of administration (i.e., routes, such as injection or implantation, that circumvent transport or diffusion through an epithelial barrier), the aqueous solution is sterile and pyrogen-free, or substantially pyrogen-free. The excipients can be chosen, for example, to effect delayed release of an agent or to selectively target one or more cells, tissues or organs. The pharmaceutical composition can be in dosage unit form such as tablet, capsule (including sprinkle capsule and gelatin capsule), granule, lyophile for reconstitution, powder, solution, syrup, suppository, injection or the like. The composition can also be present in a transdermal delivery system, e.g., a skin patch. The composition can also be present in a solution suitable for topical administration, such as an eye drop, through ophthalmic mucous membrane administration or penetration of the corneal epithelium.

A pharmaceutically acceptable carrier can contain physiologically acceptable agents that act, for example, to stabilize, increase solubility or to increase the absorption of a compound such as a compound of the invention. Such physiologically acceptable agents include, for example, carbohydrates, such as glucose, sucrose or dextrans, antioxidants, such as ascorbic acid or glutathione, chelating agents, low molecular weight proteins or other stabilizers or excipients. The choice of a pharmaceutically acceptable carrier, including a physiologically acceptable agent, depends, for example, on the route of administration of the composition. The preparation or pharmaceutical composition can be a self-emulsifying drug delivery system or a self-microemulsifying drug delivery system. The pharmaceutical composition (preparation) also can be a liposome or other polymer matrix, which can have incorporated therein, for example, a compound of the invention. Liposomes, for example, which comprise phospholipids or other lipids, are nontoxic, physiologically acceptable and metabolizable carriers that are relatively simple to make and administer.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

The phrase “pharmaceutically acceptable carrier” as used herein means a pharmaceutically acceptable material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material. Each carrier must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the patient. Some examples of materials which can serve as pharmaceutically acceptable carriers include: (1) sugars, such as lactose, glucose and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer solutions; and (21) other non-toxic compatible substances employed in pharmaceutical formulations. In certain embodiments, pharmaceutical compositions of the present invention are non-pyrogenic, i.e., do not induce significant temperature elevations when administered to a patient.

The term “pharmaceutically acceptable salt” refers to the relatively non-toxic, inorganic and organic acid addition salts of the compounds. These salts can be prepared in situ during the final isolation and purification of the compounds, or by separately reacting a purified compound in its free base form with a suitable organic or inorganic acid, and isolating the salt thus formed. Representative salts include the hydrobromide, hydrochloride, sulfate, bisulfate, phosphate, nitrate, acetate, valerate, oleate, palmitate, stearate, laurate, benzoate, lactate, phosphate, tosylate, citrate, maleate, fumarate, succinate, tartrate, naphthylate, mesylate, glucoheptonate, lactobionate, laurylsulphonate salts, and amino acid salts, and the like. Preparation of the crystalline salts is detailed in the Examples, below (See, for example, Berge et al. (1977) “Pharmaceutical Salts”, J. Pharm. Sci. 66: 1-19.).

In other cases, the compounds useful in the methods of the present invention may contain one or more acidic functional groups and, thus, are capable of forming pharmaceutically acceptable salts with pharmaceutically acceptable bases. The term “pharmaceutically acceptable salts” in these instances refers to the relatively non-toxic inorganic and organic base addition salts of a compound. These salts can likewise be prepared in situ during the final isolation and purification of the compound, or by separately reacting the purified compound in its free acid form with a suitable base, such as the hydroxide, carbonate, or bicarbonate of a pharmaceutically acceptable metal cation, with ammonia, or with a pharmaceutically acceptable organic primary, secondary, or tertiary amine. Representative alkali or alkaline earth salts include the lithium, sodium, potassium, calcium, magnesium, and aluminum salts, and the like. Other representative salts include the copper and iron salts. Representative organic amines useful for the formation of base addition salts include ethylamine, diethylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, and the like (see, for example, Berge et al., supra).

A pharmaceutical composition (preparation) can be administered to a subject by any of a number of routes of administration including, for example, orally (for example, drenches as in aqueous or non-aqueous solutions or suspensions, tablets, capsules (including sprinkle capsules and gelatin capsules), boluses, powders, granules, pastes for application to the tongue); absorption through the oral mucosa (e.g., sublingually or buccally); anally, rectally or vaginally (for example, as a pessary, cream or foam); parenterally (including intramuscularly, intravenously, subcutaneously or intrathecally as, for example, a sterile solution or suspension); nasally; intraperitoneally; subcutaneously; transdermally (for example as a patch applied to the skin); and topically (for example, as a cream, ointment or spray applied to the skin, or as an eye drop). The compound may also be formulated for inhalation. In certain embodiments, a compound may be simply dissolved or suspended in sterile water. Details of appropriate routes of administration and compositions suitable for same can be found in, for example, U.S. Pat. Nos. 6,110,973, 5,763,493, 5,731,000, 5,541,231, 5,427,798, 5,358,970 and 4,172,896, as well as in patents cited therein.

The formulations may conveniently be presented in unit dosage form and may be prepared by any methods well known in the art of pharmacy. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will vary depending upon the host being treated, the particular mode of administration. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound which produces a therapeutic effect. Generally, out of one hundred percent, this amount will range from about 1 percent to about ninety-nine percent of active ingredient, preferably from about 5 percent to about 70 percent, most preferably from about 10 percent to about 30 percent.

Methods of preparing these formulations or compositions include the step of bringing into association an active compound, such as a compound of the invention, with the carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association a compound of the present invention with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product.

Formulations of the invention suitable for oral administration may be in the form of capsules (including sprinkle capsules and gelatin capsules), cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), lyophile, powders, granules, or as a solution or a suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and/or as mouthwashes and the like, each containing a predetermined amount of a compound of the present invention as an active ingredient. Compositions or compounds may also be administered as a bolus, electuary or paste.

To prepare solid dosage forms for oral administration capsules (including sprinkle capsules and gelatin capsules), tablets, pills, dragees, powders, granules and the like), the active ingredient is mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, cetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; (10) complexing agents, such as, modified and unmodified cyclodextrins; and (11) coloring agents. In the case of capsules (including sprinkle capsules and gelatin capsules), tablets and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like.

A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binder (for example, gelatin, microcrystalline cellulose, or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent.

The tablets, and other solid dosage forms of the pharmaceutical compositions, such as dragees, capsules (including sprinkle capsules and gelatin capsules), pills and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical-formulating art. They may also be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile, other polymer matrices, liposomes and/or microspheres. They may be sterilized by, for example, filtration through a bacteria-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions that can be dissolved in sterile water, or some other sterile injectable medium immediately before use. These compositions may also optionally contain opacifying agents and may be of a composition that they release the active ingredient(s) only, or preferentially, in a certain portion of the gastrointestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. The active ingredient can also be in micro-encapsulated form, if appropriate, with one or more of the above-described excipients.

Liquid dosage forms useful for oral administration include pharmaceutically acceptable emulsions, lyophiles for reconstitution, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredient, the liquid dosage forms may contain inert diluents commonly used in the art, such as, for example, water or other solvents, cyclodextrins and derivatives thereof, solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof

Besides inert diluents, the compositions of the present invention can also include adjuvants such as wetting agents, lubricants, emulsifying and suspending agents such as sodium lauryl sulfate and magnesium stearate, or sweetening, flavoring, coloring, perfuming, preservative, or anti-oxidant agents.

Suspensions, in addition to the active compounds, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.

Formulations of the pharmaceutical compositions for rectal, vaginal, or urethral administration may be presented as a suppository, which may be prepared by mixing one or more active compounds with one or more suitable nonirritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or a salicylate, and which is solid at room temperature, but liquid at body temperature and, therefore, will melt in the rectum or vaginal cavity and release the active compound.

Formulations of the pharmaceutical compositions for administration to the mouth may be presented as a mouthwash, or an oral spray, or an oral ointment.

Alternatively, or additionally, compositions can be formulated for delivery via a catheter, stent, wire, or other intraluminal device. Delivery via such devices may be especially useful for delivery to the bladder, urethra, ureter, rectum, or intestine.

Formulations which are suitable for vaginal administration also include pessaries, tampons, vaginal rings for sustained-release (e.g., polymeric vaginal rings) creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be appropriate.

Dosage forms for the topical or transdermal administration include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active compound may be mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants that may be required.

The ointments, pastes, creams and gels may contain, in addition to an active compound, excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.

Powders and sprays can contain, in addition to an active compound, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.

The compounds described herein can be alternatively administered by aerosol. This is accomplished by preparing an aqueous aerosol, liposomal preparation, or solid particles containing the composition. A nonaqueous (e.g., fluorocarbon propellant) suspension could be used. Sonic nebulizers are preferred because they minimize exposing the agent to shear, which can result in degradation of the compound.

Ordinarily, an aqueous aerosol is made by formulating an aqueous solution or suspension of the agent together with conventional pharmaceutically acceptable carriers and stabilizers. The carriers and stabilizers vary with the requirements of the particular composition, but typically include nonionic surfactants (Tweens, Pluronics, sorbitan esters, lecithin, Cremophors), pharmaceutically acceptable co-solvents such as polyethylene glycol, innocuous proteins like serum albumin, oleic acid, amino acids such as glycine, buffers, salts, sugars, or sugar alcohols. Aerosols generally are prepared from isotonic solutions.

Transdermal patches have the added advantage of providing controlled delivery of a compound of the present invention to the body. Such dosage forms can be made by dissolving or dispersing the active compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate of such flux can be controlled by either providing a rate controlling membrane or dispersing the compound in a polymer matrix or gel.

Ophthalmic formulations, eye ointments, powders, solutions and the like, are also contemplated as being within the scope of this invention. Exemplary ophthalmic formulations are described in U.S. Publication Nos. 2005/0080056, 2005/0059744, 2005/0031697 and 2005/004074 and U.S. Pat. No. 6,583,124, the contents of which are incorporated herein by reference. If desired, liquid ophthalmic formulations have properties similar to that of lacrimal fluids, aqueous humor or vitreous humor or are compatible with such fluids. A preferred route of administration is local administration (e.g., topical administration, such as eye drops, or administration via an implant).

The phrases “parenteral administration” and “administered parenterally” as used herein means modes of administration other than enteral and topical administration, usually by injection, and includes, without limitation, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal, intravitreal and intrasternal injection and infusion. Pharmaceutical compositions suitable for parenteral administration comprise one or more active compounds in combination with one or more pharmaceutically acceptable sterile isotonic aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.

The phrases “systemic administration,” “administered systemically,” “peripheral administration” and “administered peripherally” as used herein mean the administration of a ligand, drug, or other material other than directly into the central nervous system, such that it enters the patient's system and thus, is subject to metabolism and other like processes, for example, subcutaneous administration.

Examples of suitable aqueous and nonaqueous carriers that may be employed in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials, such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, metacresol, benzoic acid and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents that delay absorption such as aluminum monostearate and gelatin.

In some cases, in order to prolong the effect of a drug, it is desirable to slow the absorption of the drug from subcutaneous, intravitreal or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material having poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution, which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.

Injectable depot forms are made by forming microencapsulated matrices of the subject compounds in biodegradable polymers such as polylactide-polyglycolide. Depending on the ratio of drug to polymer, and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissue.

The preparations of agents may be given orally, parenterally, topically, or rectally. They are, of course, given by forms suitable for each administration route. For example, they are administered in tablets or capsule form, by injection, inhalation, eye lotion, ointment, suppository, infusion; topically by lotion or ointment; and rectally by suppositories. Oral administration is preferred.

For use in the methods of this invention, active compounds can be given per se or as a pharmaceutical composition containing, for example, 0.1 to 99.5% (more preferably, 0.5 to 90%) of active ingredient in combination with a pharmaceutically acceptable carrier.

Methods of introduction may also be provided by rechargeable or biodegradable devices. Various slow release polymeric devices have been developed and tested in vivo in recent years for the controlled delivery of drugs, including proteinacious biopharmaceuticals. A variety of biocompatible polymers (including hydrogels), including both biodegradable and non-degradable polymers, can be used to form an implant for the sustained release of a compound at a particular target site.

These compounds may be administered to humans and other animals for therapy by any suitable route of administration, including orally, nasally, as by, for example, a spray, rectally, intravaginally, parenterally, intracisternally, and topically, as by powders, ointments or drops, including buccally and sublingually.

Regardless of the route of administration selected, the compounds, which may be used in a suitable hydrated form, and/or the pharmaceutical compositions of the present invention, are formulated into pharmaceutically acceptable dosage forms by conventional methods known to those of skill in the art.

Actual dosage levels of the active ingredients in the pharmaceutical compositions may be varied so as to obtain an amount of the active ingredient that is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration, without being toxic to the patient.

The selected dosage level will depend upon a variety of factors including the activity of the particular compound or combination of compounds employed, or the ester, salt or amide thereof, the route of administration, the time of administration, the rate of metabolism or excretion of the particular compound(s) being employed, the duration of the treatment, other drugs, compounds and/or materials used in combination with the particular compound(s) employed, the age, sex, weight, condition, general health and prior medical history of the patient being treated, and like factors well known in the medical arts. In general, the compositions of this invention may be provided in an aqueous solution containing about 0.1-10% w/v of a compound disclosed herein, among other substances, for parenteral administration. Typical dose ranges are from about 0.01 to about 50 mg/kg of body weight per day, given in 1 single or 2-4 divided doses. Each divided dose may contain the same or different compounds of the invention.

A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the therapeutically effective amount of the pharmaceutical composition required. For example, the physician or veterinarian could start doses of the pharmaceutical composition or compound at levels lower than that required in order to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved. A “therapeutically effective amount” of a compound with respect to the subject method of treatment, refers to an amount of the compound(s) in a preparation which, when administered as part of a desired dosage regimen (to a mammal, preferably a human) alleviates a symptom, ameliorates a condition, or slows the onset of disease conditions according to clinically acceptable standards for the disorder or condition to be treated or the cosmetic purpose, e.g., at a reasonable benefit/risk ratio applicable to any medical treatment. It is generally understood that the effective amount of the compound will vary according to the weight, sex, age, and medical history of the subject. Other factors which influence the effective amount may include, but are not limited to, the severity of the patient's condition, the disorder being treated, the stability of the compound, and, if desired, another type of therapeutic agent being administered with the compound of the invention. A larger total dose can be delivered by multiple administrations of the agent. Methods to determine efficacy and dosage are known to those skilled in the art (Isselbacher et al. (1996) Harrison's Principles of Internal Medicine 13 ed., 1814-1882, herein incorporated by reference).

In general, a suitable daily dose of an active compound used in the compositions and methods of the invention will be that amount of the compound that is the lowest dose effective to produce a therapeutic effect or the maximally tolerated dose. Such an effective dose will generally depend upon the factors described above.

If desired, the effective daily dose of the active compound may be administered as one, two, three, four, five, six or more sub-doses administered separately at appropriate intervals throughout the day, optionally, in unit dosage forms. In certain embodiments of the present invention, the active compound may be administered two or three times daily. In preferred embodiments, the active compound will be administered once daily.

The patient receiving this treatment is any animal in need, including primates, in particular humans, and other mammals such as equines, cattle, swine and sheep; and poultry and pets in general.

In certain embodiments, compounds of the invention may be used alone or conjointly administered with another type of therapeutic agent. As used herein, the phrase “conjoint administration” refers to any form of administration of two or more different therapeutic compounds such that the second compound is administered while the previously administered therapeutic compound is still effective in the body (e.g., the two compounds are simultaneously effective in the patient, which may include synergistic effects of the two compounds). For example, the different therapeutic compounds can be administered either in the same formulation or in a separate formulation, either concomitantly or sequentially. In certain embodiments, the different therapeutic compounds can be administered within one hour, 12 hours, 24 hours, 36 hours, 48 hours, 72 hours, or a week of one another. Thus, an individual who receives such treatment can benefit from a combined effect of different therapeutic compounds.

This invention includes the use of pharmaceutically acceptable salts of compounds of the invention in the compositions and methods of the present invention. In certain embodiments, contemplated salts of the invention include, but are not limited to, alkyl, dialkyl, trialkyl or tetra-alkyl ammonium salts. In certain embodiments, contemplated salts of the invention include, but are not limited to, L-arginine, benenthamine, benzathine, betaine, calcium hydroxide, choline, deanol, diethanolamine, diethylamine, 2-(diethylamino)ethanol, ethanolamine, ethylenediamine, N-methylglucamine, hydrabamine, 1H-imidazole, lithium, L-lysine, magnesium, 4-(2-hydroxyethyl)morpholine, piperazine, potassium, 1-(2-hydroxyethyl)pyrrolidine, sodium, triethanolamine, tromethamine, and zinc salts. In certain embodiments, contemplated salts of the invention include, but are not limited to, Na, Ca, K, Mg, Zn, Cu, Fe or other metal salts.

The pharmaceutically acceptable acid addition salts can also exist as various solvates, such as with water, methanol, ethanol, dimethylformamide, dichloromethane, acetonitrile, acetone, ethyl acetate, cyclopentyl methyl ether and the like. Mixtures of such solvates can also be prepared. The source of such solvate can be from the solvent of crystallization, inherent in the solvent of preparation or crystallization, or adventitious to such solvent.

Wetting agents, emulsifiers and lubricants, such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, release agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the compositions.

Examples of pharmaceutically acceptable antioxidants include: (1) water-soluble antioxidants, such as ascorbic acid, cysteine hydrochloride, sodium bisulfate, sodium metabisulfite, sodium sulfite and the like; (2) oil-soluble antioxidants, such as ascorbyl palmitate, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate, alpha-tocopherol, and the like; and (3) metal-chelating agents, such as citric acid, ethylenediamine tetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid, and the like.

The invention now being generally described, it will be more readily understood by reference to the following examples which are included merely for purposes of illustration of certain aspects and embodiments of the present invention, and are not intended to limit the invention.

Focus-Diverg. Slit [mm]: 91.00     -   Incident Beam Monochromator: No     -   Spinning: No         Polarized Light Microscopy (PLM)

The presence of birefringence was determined using an Olympus BX50 polarizing microscope, equipped with a Motic camera and image capture software (Motic Images Plus 2.0). Material was dispersed in silicone oil prior to image capture. All images were recorded using the 20× objective, unless otherwise stated.

Thermogravimetric/Differential Thermal Analysis (TG/DTA)

Approximately 5 mg of material was weighed into an open aluminum pan and loaded into a Seiko TGA6200 simultaneous thermogravimetric/differential thermal analyzer (TG/DTA) and held at room temperature. The sample was then heated at a rate of 10° C./min from 20° C. to 300° C. during which time the change in sample weight was recorded along with any differential thermal events (DTA). Nitrogen was used as the purge gas, at a flow rate of 300 cm3/min.

Differential Scanning Calorimetry (DSC)

Approximately 5 mg of material was weighed into an aluminum DSC pan and sealed nonhermetically with a pierced aluminum lid. The sample pan was then loaded into a Seiko DSC6200 (equipped with a cooler) and held at 20° C. Once a stable heat-flow response was obtained, the sample and reference were heated to ca. 190° C. at a scan rate of 10° C./min and the resulting heat flow response monitored. Nitrogen was used as the purge gas, at a flow rate of 50 cm3/min.

Karl Fischer Coulometric Titration (KF)

Approximately 10-15 mg of solid material was accurately weighed into a glass weigh-boat. The solid was then manually introduced into the titration cell of a Mettler Toledo C30 Compact Titrator. The weigh-boat was back-weighed after the addition of the solid and the weight of the added solid entered on the instrument. The titration was initiated once the sample had fully dissolved in the cell. The water content was calculated automatically by the instrument as a percentage and the data printed.

¹H Nuclear Magnetic Resonance Spectroscopy (1H NMR)

¹H-NMR spectroscopic experiments were performed on a Bruker AV500 (frequency: 500 MHz). Experiments were performed in D₂O and each sample was prepared to ca. 10 mM concentration.

Dynamic Vapor Sorption (DVS)

Approximately 10 mg of sample was placed into a mesh vapor sorption balance pan and loaded into a DVS-1 dynamic vapor sorption balance by Surface Measurement Systems. The sample was subjected to a ramping profile from 40-90% relative humidity (RH) at 10% increments, maintaining the sample at each step until a stable weight had been achieved (99.5% step completion). After completion of the sorption cycle, the sample was dried using the same procedure to 0% RH and then a second sorption cycle back to 40% RH. The weight changes during the sorption/desorption cycles were plotted, allowing the hygroscopic nature of the sample to be determined. XRPD analysis was then carried out on the remaining solid.

Gravimetric Vapor Sorption (GVS)

Approximately 10-20 mg of sample was placed into a mesh vapor sorption balance pan and loaded into an IGASorp Moisture Sorption Analyzer balance by Hiden Analytical. The sample was subjected to a ramping profile from 5-90% relative humidity (RH) at 10% increments, maintaining the sample at each step until a stable weight had been achieved (98% step completion). After completion of the sorption cycle, the sample was dried using the same procedure to 0% RH, and finally taken back to 40% RH. The weight changes during the sorption/desorption cycles were plotted, allowing the hygroscopic nature of the sample to be determined. XRPD analysis was then carried out on the remaining solid.

Example 2. General Procedure for the Preparation of Crystalline Forms

MTP-131 was charged to a vial in a glovebag under nitrogen and slurried in the appropriate solvent at 20° C.

solution of the counterion was charged was added dropwise to the vial containing the material (homogeneity solvent dependent). The slurry was stirred at 27±7° C. to achieve dissolution. In some cases, a co-solvent such as water was added incremental to achieve dissolution. The solution was temperature cycled between 40 and 0° C. The material was isolated through filtration using a Buchner funnel, rinsed with the appropriate solvent and then dried under vacuum at ambient temperature for 58 h before characterization. A portion of the material was further dried at 40° C. for ca. 48 h and then analyzed by TG/DTA.

Example 3. Small-Scale Tosylate Salt Synthesis

-   -   The tosylate salt (500 mg scale) was prepared using IPA with         water as the co-solvent to achieve dissolution.     -   Powder X-ray diffraction pattern and XRPD peaks with relative         intensities of the crystalline tosylate form thus prepared are         shown in FIG. 9 and Table 3, respectively.

Example 4. Further Small-Scale Fumarate Salt Synthesis

-   -   The fumarate salt was prepared on 35 mg scale.     -   Different ratios of fumaric acid were used as indicated in Table         D.     -   For experiments yielding solid material were isolated by         centrifugation and analyzed by XRPD.

After stirring at 20° C. for 2.5 h, slurries were fully dissolved through the addition of water, with further organic solvent added if separation occurred (Reactions 5 and 7). After temperature cycling overnight, solid material was isolated from Reactions 4-6 and 8. Pattern 3 was isolated from Reactions 1-4 and 5, with new patterns isolated from Reactions 6 and 8. After adding additional IPA to Reaction 7 and temperature cycling overnight, solid material corresponding to another new pattern was isolated.

Example 5. Preparation of Fumarate Pattern 3

-   -   The fumarate salt (500 mg scale) was prepared using IPA with         water as the co-solvent to achieve dissolution.     -   After 1 h stirring at ambient temperature, mixing was poor as         the material had precipitated to give a thick slurry. Aliquots         of IPA were added until solvent composition was IPA-water         (˜4:1).     -   Stirred at ambient temperature (ca. 23° C.) for 17 h, then         isolated through filtration using a Buchner funnel, rinsed with         IPA and then dried under vacuum at ambient temperature for 22.5         h before characterization.

A broad,         poorly crystalline pattern was obtained in each case.     -   HPLC analysis of samples after stability testing at 40° C./75%         RH indicated that the sample from methanol had a purity of         91.1%, the sample from IPA had a purity of 97.2% and the sample         from acetone:water 90:10 v/v had a purity of 99.2%.

IPA was also visible in the spectrum.     -   DVS analysis of the fumarate salt showed it to be hygroscopic,         with a change in mass of ca. 11.5% between 20-90% RH.     -   Post-DVS XRPD analysis of the fumarate salt showed it remained         Pattern 4 after the DVS experiment, although loss of         crystallinity was observed. The physical appearance of the         post-DVS material was unchanged.     -   KF analysis of the fumarate salt gave a water content of ca.         7.5% (average of 3 samples run). As the TGA shows mass loss of         ca. 8.3% before decomposition this loss is likely mostly water,         with some IPA also present.     -   By HPLC analysis, the purity of the fumarate salt was 99.9%.         Procedure 3:     -   Using Procedure 3, a large amount of precipitate formed after         dissolving the slurry with water and stirring at ambient         temperature (ca. 23° C.) for 1 h. XRPD analysis of a sample of         this solid indicated that it was poorly crystalline Pattern 3.     -   After recrystallizing using water/IPA and stirring at ambient         temperature (ca. 23° C.) for 17 h, XRPD analysis of a sample         indicated that it was crystalline Pattern 3.     -   After isolation and drying at ambient temperature for 22.5 h,         0.26 g of material was obtained (42% yield, based on 3 eq. of         fumarate).     -   XRPD analysis of the dried material indicated that it was         Pattern 4. This batch of material was used in the solubility and         hydration studies.

Example 16. Stability Testing

The scaled-up tosylate and fumarate salts were subjected to 7-day stability testing at 40° C./75% RH, 80° C. and ambient temperature and light. The following observations and results were obtained during these stability tests:

-   -   Post-stability XRPD analysis of the tosylate samples indicated         that input Pattern 1 was unchanged after stability testing.     -   Post-stability HPLC analysis of the tosylate samples indicated         that there was a slight decrease (<0.5%) in purity after         stability testing at 80° C. and ambient light/temperature. A         decrease in purity of ca. 1.3% after stability testing at 40°         C./75% RH was observed.     -   Post-stability XRPD analysis of the fumarate samples indicated         that input Pattern 4 was unchanged at lower temperatures, with         no significant crystallinity loss at 40° C./75% RH, or under         ambient conditions. At 80° C., a loss of crystallinity was         observed.     -   Post-stability HPLC analysis of the fumarate samples indicated         that there was a slight decrease (<0.5%) in purity after         stability testing at ambient light/temperature and a decrease in         purity of ca. 2.4% after stability testing at 40° C./75% RH.         However, a significant decrease in purity of ca. 17% was         observed after stability testing at 80° C.

Example 17. Salt Disproportionation Studies

The scaled-up tosylate and fumarate salts were subjected to salt disproportionation studies at ambient temperature. The following observations and results were obtained during these disproportionation studies:

-   -   After stirring the tosylate salt at 20° C. in deionized water         for 30 min, pH=2.58. After 20 h at 20° C., pH was re-measured         and was found to be 2.53.     -   XRPD analysis of the post-slurry tosylate material indicated         that there was no change to the input Pattern 1 material.     -   After stirring the fumarate salt at 20° C. in deionized water         for 30 min, pH=3.50. After 20 h at 20° C., pH was re-measured         and was found to be 3.48.     -   XRPD analysis of the post-slurry fumarate material indicated         that the input Pattern 4 material had changed to a new pattern         (designated Pattern 5), suggesting further hydrate formation.

Example 18. Hydration Studies

Hydration studies in IPA at 3 different water activities (aw=0.368, 0.608 and 0.911) were carried out using the scaled-up tosylate and fumarate salts at ambient temperature. The following observations and results were obtained during these hydration studies:

-   -   After stirring the tosylate salt at 20° C. for 25 h in each of         the IPA/water mixtures prepared, XRPD analysis of the isolated         solids indicated that input Pattern 1 was unchanged after         hydration studies.     -   After stirring the fumarate salt at 20° C. for 24 h in each of         the IPA/water mixtures prepared, XRPD analysis of the isolated         solids indicated that input Pattern 4 had changed after the         hydration studies. Pattern 3 was obtained at lower aw values         (aw=0.368 and 0.608), while Pattern 5 was obtained at aw=0.911,         suggesting further hydration occurred. The analysis was carried         out on damp solids and it is likely that Pattern 3 would convert         back to Pattern 4 after drying.

Example 19. Thermodynamic Solubility Studies

Thermodynamic solubility studies in buffers at 3 different pH values (pH=1.2, 4.5 and 6.8) were carried out using the scaled-up tosylate and fumarate salts at ambient temperature. The following observations and results were obtained during these thermodynamic solubility studies:

-   -   After creating slurries of the tosylate salt and stirring at         20° C. for ca. 15 min, pH values were checked and found to be         1.21, 4.23 and 6.55, respectively.     -   Adjusted tosylate slurries to pH 4.51 and 6.81, adding more         tosylate salt to pH=4.5 reaction to saturate.     -   After stirring the tosylate salt at 20° C. for 22 h in each         buffer solution, pH values checked again and found to be 1.22,         4.41 and 6.56, so adjusted final slurry to pH 6.76.     -   After stirring the tosylate salt at 20° C. for 24 h in each         buffer solution, XRPD analysis of the isolated solids indicated         that input Pattern 1 was unchanged after thermodynamic         solubility studies. HPLC analysis of the solutions indicated         that the solubility of the tosylate salt was relatively         unchanged by pH, with each pH giving a concentration of ca. 25         mg/mL (see Table 10 for details).     -   After creating slurries of the fumarate salt and stirring at         20° C. for ca. 15 min, pH values were checked and found to be         3.36, 3.63 and 3.73, respectively.     -   Adjusted fumarate slurries to pH 1.26, 4.51 and 6.88, adding         more fumarate salt to pH=4.5 and 6.8 reactions to saturate.     -   pH values for reactions which had more solid added were checked         again and found to be 3.36 and 4.50, so pH was adjusted to 4.41         and 6.76. All material dissolved in pH 6.8 buffer solution,         could not be saturated.     -   After stirring the fumarate salt at 20° C. for 22 h in each         buffer solution, pH values checked again and found to be 1.48,         4.45 and 6.56, so adjusted first slurry to pH 1.17.     -   After stirring the fumarate salt at 20° C. for 24 h in each         buffer solution, XRPD analysis of the isolated solids indicated         that input Pattern 4 was changed by the thermodynamic solubility         studies. pH 1.2 buffer solution resulted in isolation of fumaric         acid only, while pH 4.5 buffer solution resulted in isolation of         Pattern 5. No solid was isolated from pH 6.8 reaction.     -   HPLC analysis of the solutions indicated that the solubility of         the fumarate salt increases as the pH increases, with         solubility>173 mg/mL at pH 6.8.

Example 40. Preparation of Tosylate Pattern 2

MTP-131 tosylate (35 mg) was dissolved in the minimum quantity of methanol in a 20 mL clear glass vial and tBME (approx. 300 μL) added until slight turbidity was noticed. This vial was capped and temperature cycled between 5 and 30° C. After one week, lath-like crystals were noted to have grown below the solution meniscus, that appeared suitable for interrogation by single crystal X-ray diffraction.

Example 41. Single Crystal X-Ray Analysis (SXRD) of Tosylate Pattern 2

A colourless fragment of a lath (0.46×0.07×0.03 mm) was used in the single crystal diffraction study. The crystal was coated with Paratone oil and data collected on a Rigaku Oxford Diffraction (Dual Source) SuperNova diffractometer using mirror monochromated Cu Kα (λ=1.54184 Å, 40 kV/40 mA) radiation at 120(1) K using an Oxford Cryosystems 700+ low temperature device and Atlas CCD plate detector (Rigaku Oxford Diffraction). A total of 2672 frames were collected for a hemisphere of reflections using a ω strategy calculated by CrysAlisPro (Rigaku Oxford Diffraction 1.171.38.43h, 2015) over the θ range 3.14-77.17° with 1° step size and 2 sec/frame exposure. Frames were integrated using CrysAlisPro (Rigaku Oxford Diffraction 1.171.38.43h, 2015) to a monoclinic cell using a moving average background, yielding a total of 52633 reflections, of which 17979 were independent (I>2σ(I)). Data were integrated to 2θmax=154.34° (95.3% completeness), and fixed to 2θfull=98.1° (98.1% completeness). Absorption corrections were applied using SADABS (Bruker 2001. Bruker AXS Inc., Madison, Wis., USA) using a multi-scan model (absorption coefficient=1.732 mm-1).

The OLEX2 graphical software package was used as an interface for phase determination and structure refinement. Data were solved using direct methods (SHELXS97) and developed by full least squares refinement on F2 (SHELXL97) in the monoclinic space-group P21 (E2−1=0.731). A search for higher metric symmetry using the ADDSYMM routine of PLATON was attempted, but failed to uncover any higher order symmetry. All non-hydrogen atoms were located in the Fourier map and their positions refined prior to describing their thermal movement of all non-hydrogen atoms anisotropically. Within the asymmetric unit, one complete, crystallographically independent MTP-131 formula unit, three associated p-tolyl-counterions, one fully occupied water molecule and one fully occupied methanol molecule were found. No disorder was modelled in the final structure. All hydrogen atoms were placed in calculated positions using a riding model with fixed Uiso at 1.2 times for all CH and CH₂ groups, and 1.5 times for all CH₃ and OH groups. The Flack parameter was refined to 0.017(10) for 4760 select quotients. Note: The Flack parameter is used to determine chirality of the crystal studied, the value should be near 0, a value of 1 means that the stereochemistry is wrong and the model should be inverted. A value of 0.5 means that the crystal consists of a racemic mixture of the two enantiomers. The highest residual Fourier peak was found to be 0.39 e.Å⁻³ approx. 0.87 Å from O(9), and the deepest Fourier hole was found to be −0.45 e.Å⁻³ approx. 0.71 Å from S(3).
